That is correct. There are no modern utility scale turbines that are directly coupled to the grid. This was at least initially to allow for variable rotor speed at a constant grid frequency.

Some use doubly-fed induction generators which take about 1/3 of the power through an inverter at variable frequency back through the rotor to create stable 50 or 60 Hz output (Type 3 machines), while others do full scale conversion (Type 4 machines)[1].

FERC 827[2] details the power factor requirements in the US for non-spinning (mostly renewable) generators, most easily summarized as power factors from 0.95 lagging to 0.95 leading at the high side of the transformer in the project substation.
